SPINNINGiSPINDLE.

SPECIFICATION forming part 0f Letters Patent No. 658,597, dated September 25, 1900.

Application tiled December 14, 1899. serial No. 740,267. (No model.)

To al?, whom t may concern:

Be it known that I, CYRUS E. SMITH, a citi- Zen of the United States, residing at Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Spinning-Spindles, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

This invention relates to spinning-spindles, and more especially to a means to insure the proper even operation of the spindle and bobbin, the construction being such that the entrance of waste, tiyings, dirt, tbc., into the space between the bobbin and bolster or the bolster and the spindle is positively prevented, as in such a case as this the parts would become clogged and their action more or less affected.

My invent-ion, as shown in one simple embodiment and hereinafter described, comprises a spindle in combination with a bolster and a clearer or device cooperating therewith and serving to positively prevent the entrance of waste between said spindle and bolster to impede their rotation, and said clearer or device may be of any suitable shape or character, though for simplicity I prefer to make it in the form of a spiral spring, which is so shaped with relation to the direction of rotation ot' the spindle as to preclude any dirt that may come in contact with the spindle at the ends of the bolster from entering the space between the spindle and bolster, and it' for any reason flyings should get into the said space the spindle in its rotation carrying the Waste with it will cause the waste to be discharged from the spaces in the bolster.

In the drawings, wherein I have represented my improvements in a simple form thereof, Figure lis a longitudinal centralhsectional elevation ot a spindle equipped with two of my clearers or devices. Fig. 2 is an enlarged detail showing the lower end of the bolster and its clearer and part of the spindle. Fig. 3 is an enlarged detail showing the upper end of the bolster, its clearer, and part of the bobbin and spindle. Figs. 4 and 5 are sections taken in the lines i4 and 5 5 in Figs. 2 and 3, respectively. Figs. 6 and 7 are detail-views of the lower and upper ends, respectively, of the bolster, showing a means whereby the clearers may be secured in place.

In t-he drawings I have shown in Fig. l-the principal parts of a common type of spindle. The lifting-frame is denoted by L. 12 represents the spindle proper, stepped in the bearing 13 and surrounded longitudinally by the relatively-stationary bolster 14:. The bolster at its lower end passes through the hub or sleeve 15, and it has a circumferential shoulder 16 fitting against the upper side of said hub, the latter havinga shank 17 flanged, as at 18, the flange being secured by means of a bolt 19 to the lift.ing-rail. The bolsteil 14 is confined to the lifting-rail, which is reciproeated to move the bolster and bobbin longitudinally of the rotating spindle by a holding-nut 2O in threaded engagement with the bolster, said nut being maintained in proper position by a check-nut 2l.

In Figs. 2 and 3 I have indicated by the arrow the direction of rotation of the spindle l2, and in Fig. 1 I have shown a bevel-gear 22, constituting a part of a convenient means for driving the spindle, the bolster 14 being surrounded loosely by the bobbin 23, the lower end of whichv enters or is operatively engaged with the upper end of `a bevel-gear 24, constituting part of the means for rotating the bobbin.

The parts hereinbefore described constitute a spinning-spindle of old construction, to which my improvement-s are well adapted, though said improvements can be used in connection with many other kinds of spindles or analogous devices where it is essential that waste, tlyings, and other foreign matter, be excluded from between the spindle and bolster.

The bolster 14 is shown as having iu its upper and lower ends, respectively, enlarged chambers 25 and 26, in which are located clearers 27 and 28, each of said clearers being herein represented as consisting of a spiral feeder constructed in the form approximately of a coiled spring, this being an inexpensive type of clearer or waste-excluding member. The clearers are operative to preventthe entrance of all kinds of foreign matter into the oil-chambers at the ends of the bolster, and they serve, each of them, when any flying IOO particles lodge on the spindle at the ends of the bolster to positively screw or force said particles in opposite directions or upward and downward, respectively, with relation to the spindle, and consequently away from the ends of the bolster. The clearers surround .the spindle l2 and are contiguous to the periphery of the same near the opposite ends of the bolster, and they are conveniently connected to the latter, and in Figs. 6 and 7, where I have represented in detail the upper and lower ends of the bolster 14, said end s'have bayonet or curved slots 29 and 30, the slot 30 being adapted to receive the end of the topmost coil of the clearer 28, while the slot 29 is adapted to receive the end of the lower coil of the Iowermost clearer, and the ends of said clearers have offsets, as 27 and 28', t0 enter saidslots. By this construction the clearers may readily be removed by giving them a very slight turn or a turn sufficient to carry the offsets thereot out of the slots in which they are normally located, and they may be as easily replaced in position should it be desired to clean them of adhering particles of dirt.

The springs constituting the clearers are of dierent pitch, the upper one in the present case being of a right-hand pitch, while the `combined with right, and left hand spiral clear-ers surrounding the spindle and inclosed lower one is of a left-hand pitch, such diierence in pitch enabling the spindle turning in but one direction to force the foreign matter coming thereagainst in opposite directions. The clearers also serve another functionthat is, by reason of their contact with the rotating spindle they prevent the oil on the spindle from running too freely down the same, the coils of the springs contacting with the periphery of the spindle and acting thereby to hold, applied in usual manner, the oil for the purpose of lubricating the parts.

I nd that one oiling will last several days, because the oil is retained between the coils of the spring, whereas with the usual bolster,

not provided with such s rings, the spindle needs oiling everyday, an further, it will be noticed that the wire of the springs contacts with the spindle and with the inner wall of the chamber in the bolster, said wire constistuting t-he sole bearing between the spindle and bolster, and consequently the wear on the bolster and spindle is greatly lessened.

The invention is not limited to the precise construction, for this may be materially modified within the scope of the accompanying claims.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A spindle, and a bolster combined with a clearer to prevent the accumulation of waste to the bearing-surfaces between the spindle and bolster and operating during the relative movement of the spindle and bolster to force any waste outward from the bearing-surfaces.

2. A spindle, and a bolster combined with a spiral clearer surrounding the spindle and inclosed by and connected with said bolster.

3. A spindle and a bolster1 combined with right and left hand spiral clearer-s surrounding the spindle and inclosed by the bolster.

4. A spindle, and a bolster having slots,

by the bolster, the end coils of the spiral clearers being disposed in said slots.

5. A bolster having at its ends spiral springs, combined with a spindle, said springs constituting the lateral bearings between the spindle and bolster.

In testimony whereof I have signed my name to this specification in the presence of two, subscribing witnesses.

CYRUS E. SMITH.
